About the role
Why Castelion, Why Now Castelion is moving incredibly fast to develop and deliver advanced defense systems at a time when execution matters more than ever. We believe focus and technical excellence are decisive advantages - and we are building a team that can deliver real capability, not just concepts. This is a rare opportunity to join at an early stage, where your work will directly shape critical systems, influence major technical decisions, and have immediate, real-world impact. Electrical Engineer As an Electrical Engineer , you will become the Responsible Engineer for multiple mission-critical circuit card assemblies (CCAs) that power Castelion's flight systems. While the initial designs have been completed, you'll take ownership of the products through qualification, production readiness, and full-rate manufacturing. This is an exceptional opportunity for an early-career engineer to gain end-to-end product ownership at a rapidly growing aerospace company. You'll work closely with experienced electrical, manufacturing, quality, and supply chain engineers to transition complex electronics from prototype to production while ensuring reliability, manufacturability, and long-term support. At Castelion, engineers own their hardware throughout its entire lifecycle—from design refinement and qualification through production, field support, and continuous improvement.
Responsibilities Serve as the Responsible Engineer for multiple circuit card assemblies (CCAs) supporting flight hardware. Drive electronic hardware through design verification, qualification, and production readiness. Support environmental, electrical, and functional qualification testing and document test results. Partner with Quality Engineering to establish production metrics, acceptance criteria, and manufacturing quality processes. Support the transition of electronic hardware into Low Rate Initial Production (LRIP) and Full Rate Production (FRP). Investigate and resolve manufacturing, production, and supplier issues to ensure uninterrupted hardware delivery. Collaborate with component manufacturers and suppliers to address obsolescence, availability, and technical challenges. Update schematics and documentation to improve manufacturability, reliability, and component availability. Review PCB layouts and schematic designs to ensure compliance with design intent and manufacturing best practices. Support root cause investigations, corrective actions, and continuous improvement initiatives. Work cross-functionally with electrical, manufacturing, quality, supply chain, and integration teams throughout the product lifecycle. Contribute to process improvements that increase product quality, production efficiency, and hardware reliability. Basic
